just lost btc through a scam wallet on google play market. if you type in 'bitcoin wallet'. you'll see SoBit: Bitcoin Wallet. it has 5 star rating & it would be first or second on the list. beware. once you send funds to it, it sends out btc somewhere else after confirmation. i couldnt believe it at first but then after going through 1 star reviews i realised i wasnt the only one. makes me wonder how can google allow this scam to be on top?
I'm not sure if this is the wallet that you are referencing:

Unfortunately, Google doesn't moderate it, so the best thing to do is to report it to them so that they can take it down. Perhaps another expensive lessons to check everything first or just used wallet that we have been trusting already like Electrum.
